To' all whom t may concern.

Be it known that I, WILLIAM EnAsrUs l/lfiLIlIAirs, a citizen of the `United States, Chicago, in the county of Cook and State of Illinois, have inventeda new anduseful improvement in Vehicle Disk Wheels, of Which the following is a specification.

My invention rela-tes to disk wheels wherev in a disk demountable from the hub i peripherally turned over andlocked to e. portion of the rim.

The object of the invention is-to produce an inexpensive, strong, easily Washed, and readily demounted structure having the hub, disk, and riin securely connected.

.Reference will be had tothe accompanying drawings in which Figure l is e front elevation ot' the wheel. Figuref is a sectional elevation. l

Figure 3 is a front elevational detail of a part of the disk.

Figure 4 is a larged scale. t

vIn the drawing l indicates the hub et" an ordinary automobile Wheel,l ere shown asv the rear hub end 2 yindicates `the brake drum. 3 indicates the-.main rini portion provided with a specially arranged quick( detachable flange 4.. of the disk. .The disk is made tapered, being thinner at its outer edge and getting thicker Atoward the center to take' cere 'of the increased moments ofresistance encountered around the hub. l

The peculiar merit ot' the rim structure is that the companion flange e, er the quickl detachable ring l is provided with a seatl 27 which enters into and under the bead of the tire and thus the load on the tire holds y cut transversely in' order to besprung in and out of its engagement with the main rim. portion.

he main rim portion is provided withY aY small flange 6 which in connection with and inclined Wall 8 provides a seat for the -projection 9 ofthe flange i and the metal ot the disk is turned over as is indicated by l0 and embraces'this lienge 6 of the main rim. Theunder portion ll of the lange 1irests'."on`tlie ,turned over metal of the edge ot' the disk and thus aids in holding the metal of the disk to its turned over or spun ever position.

The side. thrust or side pressure of a'tir'e detail of the on en en- When it is inted causes an voutward Apre`s- 5 indicates the bodyvl Specification of Letters atent. i Patgted ljfgy 16, @532% '1920. Yserial n. casses.

sure ot' the flange 4 and this causes the Harige 9 ofthe flange 4l to press sidewise against the turned over edge of the disk and also hold the same in its interlocked position.

` The nieta-l of the disk is turned into a swell 12 in the hub region and this mergesinto an inclined surface 13 which bears on to theiinclined shoulder of alange 1.4 on the hub'. The tiange ld merges into e vertical flange 15 to which the brake drum is secured through the medium of the bolts 16.@

fllie inner hub zone of the disk terminates in an inclined portion 17 which beers one hub barrel 18 and the ldisk is 'clamped to the hub by means of a, clamping ring 19 secured by round liat headed nuts EZOsecured on the outer vi6. lThese nuts 2O enter into-holes V22 in the disk and slotsl 23 in the disk at this region permit e'. slight bending of the flange l? into engagement with the hub barrel surface -18 .when the clamping ring t9 clamped tightly on to the disk. The clamping ring the disk end supportsthe latter, transferring tothe ring tension strains on the diskD lt is thus apparent'that loads on the Wheel will be shared byhcompression or strut-likeA shocks .from the outside where skid shocks are encountered and at the -same time they swelled and inclined connection of the disk v around thefhub region allows e slight degree ends 2l of the screws or bolts The nuts en nein the holes 22 f the disk 'and therefore when the nuts vare taken out 19 is provided withe vWall 2eA which overlaps the 'surface 13 of loo of elasticity in the travel of the Wheel which is a desideratum. v

l.' The combination with a hub barrel having a flange provided with an annular, in-

clined, peripheral bearing surface, of a Wheel disk provided with ay laterally inclined portion bearing on said surface andwitli a cen trally perforated portion extending obliquely outward with 'respect to the planev of the Wheel from said surface to said barrel, and aclamping ring resting against the body of said disk only near its Contact with said surface and against the hub in front of said perforated portion.

2. ln a device of the class described a detachable disk forming the web of the Wheel secured to the hub in a detachable mannerin which there is a flange on the hub liaving`an outward inclined bearing surface and a bearing surface on the hub barrel, the said disk having,` an inclined portion around the hub zone adapted to bear on the inclined surface f of' the hub flange and an inclined surface around the hub aperture of the disk; in combination With a clamping flange and means for clamping the said flange against the in'- clined surface of the disk at the hub flange and also against the margin of the inclined portion of the'V disk around the hub barrels ln a device ol' the class described a disk demountably 'secured to the hub through the medium of a 'bearing of the disk on a iiange' of the hub and simultaneous bearing of the said disk on the hub barrel, the said bearing of' the disk on the said flange of the hub beingy in an inclined direction adapted to take direct and side loads and the bearingof the disk on to the hub 'barrel adapted to take direct loads only; in combination with a clampingA flange adapted to bear on the vinclined portion of the disk at the inclined bearing on the hub -flange and to press inward the inner margin of the disk around the hub bar rel, with means for binding the said flange., disk and hub together.

4. In a device of the class described, a disk demountably secured tothe huh through the medium ot a bearing of the disk on a flange oi tbe hub and simultaneous bea-ring of the said disk on the hub barrel, the said bearing of the disk on the, said flange of the hub being inan inclined direction adapting to resist both vertical and lateral thrusts and the bearing of the disk on to the hub barrel adapted in itself to resist vertical strains only; in combinationwith a clamping flange adapted to bear on 'the inclined portion of the disk at the inclined" bearing on the hub flange and upon the hub barrel at the inner margin of the disk with clamping bolts passing, through the hub flange, disk and .clamping flange.

5. The combination with a hub provided with a flange having an oblique peripheral `face, of a disk bearing laterally upon said face, thereby resisting vertical and lateral strains, and further bearing on a non-oblique face portion of the hub supporting vertical strains only, a dlamping ring arranged for pressiincy the disk against said oblique face and inW'a-rdly along the nonfoblique face, and bolts passing through tire hub flange, disk,and clamping ring, orcing the disk and rin-g toward the hub flauge and gripping the disk firmly in two regions, and in somewhat widely separated planes.

6. The combination with a hub barrel hav-t ing a flange rovided with an annular, peripheral, inclined bearing face in the load plane. of a disk having an inclined zone fitting against said face and a less inclined central portion fitting' against a non-inclined portion of said barrel, and-a clamping ring for urging` the outer, inclined marginal por-4 tion of the disk inwardly along the hub grippingl the latter through change in the @inclination of said marginal portion, and raving at its outer margin a cylindrical lange pressing` said inclined zone, whereby the disk is clamped against the barrel and against said inclined bearing face.
